Question 1

Your distributed application emits logs, traces, and metrics using various legacy libraries. You want to achieve a unified observability pipeline without altering existing log formats. Which OpenTelemetry component should you configure to map and process these diverse telemetry signals uniformly?

A : Implement the OpenTelemetry API directly in each service.

B : Configure the OpenTelemetry Collector to ingest and map the different telemetry signals.

C : Use the OpenTelemetry SDK to replace all legacy libraries.

D : Set up separate backends for logs, traces, and metrics without using OpenTelemetry.

Answer: B

Question 2

You are a developer managing a production system that currently uses unstructured logs, making it difficult to perform scalable log analysis.
